Sorry, I don't understand your question. Where in your amplifier does a 330uf capacitor pass the whole signal?You didn't answer this question .Regarding amplifiers if a 330uf cap is passing the whole signal in such case the highs will be able to pass undistorted ?. Also before installing the 1000uf KG caps I made some measurements and ESR was 0.01 and Vloss 1.2% so I presume they are ok because de bass and sound depth was much higher compared with KZ. The problem was only with the bad high freq that was restored using those 10uf KZ caps in parallel.
It sounds like you're talking about a coupling capacitor. In capacitively-coupled amplifiers, a coupling capacitor will attenuate low frequency signals and completely block DC, which is the reason for using it. The larger the value of the capacitor, the lower the attenuation frequency. In a typical coupling configuration, it acts as a high-pass filter, so high frequencies are passed undistorted. Its value for audio circuits is typically selected so that it attenuates below 20hz.
A filter capacitor is not a coupling capacitor.
